“…This is because ofthe every pixel shine asynchronously. The angle -linear limitation for these systems can be written as 6é8x 2 (3) (Analogue to Heisenberg uncertainly principle in quantum mechanics). The comfortable angle resolution is defined by the human eye pupil dimension (about 3 mm).…”

Some principals of 3-D visualization are analyzed in this paper. A novel scanner system with special hologram transparent for 3-D visualization is proposed. Volumetric principals are utilized in this system. 3-D Cartesian co-ordinates with irregular scale in depth direction are possible used for 3-D objects describing. This approach decrease sharply demands for the information flow of dynamic 3-D scene describing.

“…One of them is there are not masks corresponding to any number of viewpoint and obvious serrations on the border of view zone. In order to solve these problems, weighted masks are used in autostereoscopic display based on partial sub-pixel [3]- [5] . As the image of each sub-pixel is between 0 and 1, the corresponding computations will be tremendously growing and unbearable for CPU.…”

With the progress of 3D technology, the huge computing capacity for the real-time autostereoscopic display is required. Because of complicated sub-pixel allocating, masks providing arranged sub-pixels are fabricated to reduce real-time computation. However, the binary mask has inherent drawbacks. In order to solve these problems, weighted masks are used in displaying based on partial sub-pixel. Nevertheless, the corresponding computations will be tremendously growing and unbearable for CPU. To improve calculating speed, Graphics Processing Unit (GPU) processing with parallel computing ability is adopted. Here the principle of partial sub-pixel is presented, and the texture array of Direct3D 10 is used to increase the number of computable textures. When dealing with a HD display and multi-viewpoints, a low level GPU is still able to permit a fluent real time displaying, while the performance of high level CPU is really not acceptable. Meanwhile, after using texture array, the performance of D3D10 could be double, and sometimes be triple faster than D3D9. There are several distinguishing features for the proposed method, such as the good portability, less overhead and good stability. The GPU display system could also be used for the future Ultra HD autostereoscopic display.

“…And also, three-dimensional (3D) display systems have focused on real-time full color auto-stereoscopic 3D displays, such as integral imaging [11,12] , holographic stereography [13,14] , partial pixel structures [15] , and micro mirror array architecture [16] . Holography is the only 3D imaging technique that is capable of providing all the depth cues and can produce images with virtually unlimited resolution.…”

Full-color autostereoscopic video display system using computer-generated synthetic phase holograms

A full-color auto-stereoscopic video display system has been introduced and developed using only a single phase-only spatial light modulator, a simple projection lens module, and three laser diode sources with the wavelengths of 635nm (red), 532nm (green), and 473nm (blue). Full-color stereoscopic input video frames are separated by each red, green, and blue component with respect to each stereo eye view for a 3D image frame. Each hologram is then optimized by a modified iterative Fresnel transform algorithm method, for the reconstruction of each gray-level quantized stereo image without color dispersion. To solve the color dispersion problem we applied scaling constraints and phase-leveling techniques for each hologram. Then the optimized holograms are synthesized with direction-multiplexed holograms and modulated by a single phase-type spatial light modulator. The modulated signals are Fourier-transformed by an achromatic lens and redirected to each viewer's eye for the reconstruction of the composed full-color auto-stereoscopic 3D display. Experimentally, we demonstrated that the designed computer-generated holograms were able to generate full-color stereoscopic 3D video images without glasses.
